MPM連軋機速度制度的探討
DISCUSSION CONCERNING VELOCITY SCHEDULE OF MPM MILL
-
摘要: 研究了影響限動芯棒連軋機速度制度的有關因素,定量分析了限動速度與芯棒預插行程、芯棒規(guī)格和荒管長度之間的關系,并分析了影響連軋機速度制度的關鍵因素——機架孔型系數Abstract: The discussion involves investigation of relevant factors influencing the velocity schedule of the retained-mandrel MPM, quantative analysis of retained speed VS mandrel-prethreading travel and mandrel size VS tube length as well as analysis of the critical factor affecting the velocity schedule of MPM, the stand pass factor.
